The invention has for its primeobject toflimprove generally upon terracing and grading machines of the rotary typef so as to increasethe efficiency of such machines and secure a better control in the operation of the machineand a p more even and advantageous distribution of the carried soil.

Another object structure without detracting from the strength i the lateral deflection and shifting of the machine in its forward travel. i i

A still further object is to secure an'equal balance of the machine and to operate the machine with no excess height izing of the dirt.

is to simplify and lighten the i of lift or pulverand durability thereof so as to minimize the i in, an'endl ess belt is substituted for the rotary drum illustrated in Figures 5, 6 and '7.

Referring'now to the drawings in detail and i more particularly to Figures 1 to 4, inclusive, the numeral I designates the main rotary disklike table element or soil carrier of the machine, the same being of an annular form, that is to say, it has a central circular opening 2 whereby its ,soilf carrying portion is annular or ringlike in form. This rotary table or soil carrier I is rotatably mounted on and within an open frame 'the longitudinal portion of which is substantially rectangular and a part of the transverse portion of the frame is substantially rectangular, the

rest of the transverse portion of the frame being of slightly different formation and open at one side thereof. That is to say, I the longitudinal portion of the frame comprises two U-shaped sections 3 and 4, respectively, with their respective leg members 3*,3", and 4 4 aligned and riveted at their inner ends, as at 3 and 4 to upper and lower circular plates 5 and 6, respectively, while the transverse portion of the frame comprises an upper bar I which is riveted, as

at "I to the upper plate '5, to which plate and diametrically opposite and in lengthwise aligni ment with the bar I,the leg member 8 of a With the foregoing and other objects and advantages to be attained, as will hereinafter more fully appear, the invention consists in the novel general structure and in the several parts and combinations and arrangements of partsthereof, as hereinafter described; and set forth with particularityin theappended claims, reference being had to the accompanyingdrawings, in which,

Figure 6 is a section taken on or about the transverse line 6-4; of Figure 5; I

Figure 7 is a section taken "on or about the longitudinal line 'I-'I of Figure 5; and I Figure 8 isa fragmentary plan view illustrating a modificationof the scraper element wherea top plan view of one form ofthe substantially U -shaped section 8 is attached, as at 8", said section 8 having a portion of its opposite leg parallel with the leg 8*", as at 9, the remainder of the leg converging toward the lower plate 6, as at9 and being attached to the plate, asat 9 with a wedge-shaped filler I'll between its end portion and the plate (see Figure 3).

The aforesaid frame structure including the aligned longitudinal sections 3 and 4 and the transverse bar 1 and section 8, connected as they are to the upper and lower plates 5 and 6, is of ample rigidity to support and carry the rotary table or soil carrier I thereon and the rigidity and stability being further enhanced by the peculiar provision in the mounting of said elemounted, saidstrut member II being secured at its opposite end portions inbores provided therefor in the central portions of the plates 5 and Ii, which portions are reinforced on the outer faces of the plates by bosses I2, the fastening of the strut 'member II in place being by any. obvious means such as cross-pins or nut members applied to the outer end portions of the member II or even by a welding process or the equivalent. The rotary table or soil carrier l is provided at the center of its opening 2 with a hub member l3 which is connected to the inner peripheral portion of said element I by a series of radial members or spokes l4, said hub member having a boss or bearing protuberance IS on its underside which rests and rotates upon the adjacent top face portion of the lower plate 6 of the main frame of the machine.

The main frame of the machine is tilted both longitudinally and transversely, that is to say, it is provided with a pair of supporting ground wheels l6 at the rear thereof which maintain the rear portion of the frame at a considerable distance above the ground, and a single ground wheel I! of much smaller diameter than-the'rear wheels l6 at the front end of the longitudinal frame section 3, said wheel I l supporting the adjacent end portion of the frame close t the ground. The wheel ll tracks in close relation to the longitudinal axis of the machine whilethe two rear wheels l6 are disposed equi-distant on opposite sides of the longitudinal axis of the machine. The front wheel IT is mounted conventionally on a lateral stub-bearing-extension I 8 located at the lower corner of the forward frame section 3 (see Figures 1 andZ). The pair of rear ground wheels I6 have a trailing casterlike mounting on the main body frame of the machine the same including downwardly and rearwardly curved forks 19 whose shank portions 29 are respectively swiveled in vertically bored bearing portions 2! provided at the rear ends of a pair of longitudinal auxiliary framemembers 22. The frame members 22 are attached at their forward ends, one to the transverse frame bar I, as at 22*, and the other likewise to the upper leg 8 of the transverse frame section 8, as at 22*, the frame member 22 which is located to the left of the longitudinal axis of the machine being, of course, in a lower plane than the other frame member 22 at the opposite side of the axis, this being due to the aforesaid transverse inclination of the main frame of the machine, and because of Which the bearing portion 2! at the end of the frame member 22 to the right of the longitudinal axis of the machine is, obviously, either located lower than the corresponding bearing portion on the opposite frame member 22 or accordingly elongated and extended downwardly if the two forks l9 are identical in size and shape, or the fork l9 which carries the wheel to the right of the longitudinal axis of the machine maybe extended upwardly to where the shank portion 20 is provided thereon.

The main body frame of the machine, in the construction and arrangement illustrated in Figures 1 to 4, inclusive, further includes a pair of diagonal, substantially U-shaped sections .23 which diverge from the upper and lower central plates and 6', the upper legs 23 and lower legs 23 of said sections 23 being secured at their inner ends to the upper and lower plates 5 and 6, respectively, as at 23, in the same manner as the hereinbefore described other frame members are attached to saidplates. The rear end portions of the diagonal frame sections 23 are cross-connected by a transverse bar 24 to which the longitudinal frame members 22 are fastened, as at 25, and there is a further bracing 26 which extends diagonally between the'rear end of the longitudinal frame section 4 and the ends of the respective diagonal frame sections 23 (see Figure 1). The longitudinal frame members 22, are

' 29 by a cross brace 32.

also secured to the diagonal braces 26, as at 21. Said longitudinal frame members 22 are also preferably secured to the diagonal frame sections 23, as at 25 where they cross the upper legs of said sections 23 (see Figures 1 and 4).

Extending laterally and perpendicularly to the left from the front end of the forward longitudinal frame section 3, is a frame bar 28, which, preferably as shown in Figure 2, is of round cross section. Secured at its forward end to the outer end of said bar 28 is a rearwardly extending longitudinal side frame bar 29, preferably of rectangular cross section, as shown more clearly in Figure 3, said longitudinal bar 29 carrying, as 15'- shown, an oblique ground scraper 36 comprising a flat plate which is secured at its upper forward portion to the bar 29, as at 3l, the scraper being attached at its upper rear end portion to the bar The lower rear corner portion of the scraper 30 is cut away, as at 33, to clear and accommodate the marginal portion of the table or soil carrier l as it travels thereunder close to the ground (see Figure 3). The longitudinal side frame bar 29, just to the rear of the cross brace 32 which connects the scraper 33 to the bar, is connected to the outer end portion of the transverse main frame bar by a bracket member 3t. Preferably, the longitudinal side frame bar 29 is extended rearwardly from the bracket 34 and connected at its end to the end of the adjacent diagonal frame section 23 by a cross brace 35, which latter is preferably aligned with the cross brace 24 connecting the ends of the two diagonal frame sections 23 (see Figure 1).

Normally, the annular table or soil carrier is supported on a ground wheel 35 at a point substantially diametrically opposite the lowermost portion of its periphery which travels close to the ground and under the cut away portion 33 of the scraper. element 36 (see Figure 3), the wheel 36, which is preferably rubber-tired, being set at an inclination so that it is substantially perpendicular to the underside of the marginal portion of the table or soil carrying element l which rests thereon and by the contact thus made between said element l and the wheel 36, the latter, in its rolling travel on the ground, imparts rotation to the element. The inclined set of the wheel 36 and its perpendicular relation to the marginal portion of the table or soil carrying element l is maintained because of it being journaled on the lower inclined leg portion 9 of the transverse frame section 8. In this connection, it is noted that the hub portion 3! of the wheel 36 is shiftable longitudinally on said leg portion 9 of the frame section 8 by and under the control of a hand lever 38 which is pivotally mounted, as at 39, on a sector bracket 40, the end portions of which latter are secured to the intermediate base portion of the frame section 8, as at 4|, and the lower end portion of the lever being pivotally attached, as at 42, to a link 43, which, in turn, is swivelly attached, as at 45, to the outer end of the hub 31 of the wheel 36. The hand lever 38is provided with a conventional latch element 45 which is engageable in the toothed portion" of' the sector whereby the lever is held in different positions to which it is moved, and said latch element being under the control of a conventional releasing lever 46 located adjacent the grasping portion of the hand lever and having the usual .rod. connection 4'1 with the latch element 45. By manipulation of the hand lever 3 8,the ground wheel 36 is shifted on the leg portion 9 of the frame section 8 in the direction to l min the opposite direction fromunder easily rotated under the driving action of the groundwheel 36, said rollers 48, other thanthat located on the framemember 3 being located in the region where the preponderanceof the load is carried onsaid element I. At the forward end of themachine is provided, the chain,{as shown, including convergentlinks 49 and 50 which are respectively attached one to the forward end portion of the longitudinal side bar 29, as at 5|, and

the other to the, front endyof thepforward longitudinalframe section .3,--,a s at 52, said links 49 and 50 being joined at their meeting endsby a ring: member 53;fo r efiecting attachment to a draft medium such as a traetoror a horse-drawn ortractor drawn or propelled plow, the links 49 and 45 being proportioned in length and the ring member 5 3 1ocated, so that the machine'of the pr'esentinvrgntion isrdrawn forward in usein a straight linewithoutundue tendency to shift late erallyfromtheline of draft. V i

Obviously, instead of providing the oblique scraper element 30, asshown in the drawings, a V-shaped drag disk-or aplowshare with'a moldboard attached thereto may be provided on the machine of the present inventi'onor the machine may be hitched to a grader provided with either an oblique or V-shaped digger or drag element or a. conventional moldboard plow which travels in alignment ahead :of the scraper element 30 or flange 54 whence it is deflected from the machine asit is brought into contact with the deflecting scraper element 56. To prevent the material from being forced rearwardly off the table orsoil carrying element l within the range of an area which extends some distance on opposite sides of the longitudinal axis of the machine, a guard 58,preferably of the endless belt type, as shown, is provided,the inner flight of the belt conforming to the arc of i the periphery of the table or soil carrying element l between a pair of supporting rollers 59, which latter arejournaled within the ,outer end portions of the diagonal U-shaped frame sections -23 (see Figures 1 and 4) the lower edge portion of the belt traveling in contact with the; periphery of the element l but the major portionpf the belt extending a considerable distance above the topface of the element to approximately the plane of the top edge of the annular guard flange 54 on the element. The arcuateflightof the belt 58 is supported midway 2 between the supporting rollers .59 by an-outer other suitable elements substituted therefor on themachine of thepresent invention, Which element 30 or its substitute, deflectsthe soil loosened ahead of it onto the rotating table or soil carrier element I, whence thematerial thereon is discharged by means to be now described.

In the structure illustrated in Figures ,1 to 4,

inclusive, the centralopening 2 of the annular table or soilcarrying element [i surrounded by an upstanding annular flange 54 which, as

shown, is provided with an inturned flange 55 at rollerfifl similar to-the rollers 59andjourna1ed just within the outer endof the longitudinal I U-shaped frame section 4 and there being an inner roller 60a journaled within the frame section 4 and of smaller diameter and length to support the upper marginal portion of the arcuate flight of the belt inthe region where it is supported by the outer roller 60. The outer flight of the belt 58 travels obliquely, as at 6|, between theroller 60 andthe respective rol1ers59 (see Figure 1). By this provision, undue crowding and jamming of the material is prevented in its travel with the rotating table or soil carrying element las the inner flight of the belt 58 travels with the periphi ery of said element 1.

A modified structure is illustrated in Figures 5, 6 and 7, wherein the main frame of the machine is substantially the same in structure as the longitudinal and transverse sections thereof which are illustrated in Figures lto 4, inclusive; that is to say, it includes front and rear substantially U-shaped sections 62 and 63, respectively, which are similar in'general to the hereinbefore described sections 3 and 4, except that the leg its lower edge, said flange resting upon the outer end portions of" the radial members or spokes M of the table or soil carrying element I and being fastened tofsaid element l by the same rivets or fasteningmeans which secure the radial members-orspokest fl to said element I. This annular flange constitutes a guard to prevent the material onjthe table or soil carrying element I from moving. therefrom through the central opening 2. .Cooperatingwith the annular flange or guard 55 is an arcuate deflecting scraper 56 which, as shown, is hingedlymounted, as at 51, ontheintermediate base'portion of the .U -shaped transverse frame section 8 ,(see Figures 1 and 3), said scraper element 56'eirtending over the top face of the table. or soil carrying element l with its lower edge portion in close scraping contiguity .thereto and the otherwise free end portion of said element 56 being insliding contact with thecircumferential facing of said annular flange or guard element 54. By this provision, when the table or soil carrying element. I rotates in the direction indicated by the arcuate arrows in Figure 1, during the forward travel of the machine,

the loosened soil whichfis deflected by the scraper element 30 onto the adjacent lowermost portion of said element! is carried by the element to therear and'to the 'rightofl the central uard members of said sections 62. and 63 are integrally joinedrat their inner ends andflattened at the joint,ias at 64. There is a further difference in thatthe bar'65, which is the equivalent of the hereinbefore described bar I, is continued with an integral horizontalextension 66which is attached directly to the longitudinal side bar 29 of the frame, as at 61, the bars 29 and carrying the scraper element 30 in the same manner that such element is mounted in the first herein describedstructure and the element 30 being cut away as at 33 the same as the hereinbefore described element 30. The transverse frame section 68 is substantially of the same form as the hereinbefore described section 8 except that both leg members thereof are integrally joined to the flattened connections between the leg members of the longitudinal frame sections 62 and 63, it

being here also noted that the bar 65 is integrally I securedat its inner end to the flattened connection between the upper leg members of the longitudinal sections 62 'and63. There is a further difference in the form of the frame section 63 in that its lower leg member (i8 is straight tion between the lower legs of the longitudinal frame sections 62 and 63, as at 69 (see Figure 6) In this modification, a ground wheel 36 is substituted in place of the hereinbefore described wheel 36, said ground wheel 3t being journaled on the convergent lower leg of the frame section 68 and being disposed more nearly vertical than the aforesaid wheel 36 but otherwise traveling on the ground and supporting and causing rotation to the annular table or soil carrying element I in substantially the same manner as the aforesaid wheel 36. The wheel 36 is not shiftable on the leg 68 of the frame section 68.

In the modification illustrated in Figures 5, 6 and '7, the central annular deflecting flange or guard 54 is dispensed with and so is the endless belt guard 58, and in place thereof a rotary drum scraper element 10 is provided, said element 10 beingin the form of a cylindrical cup having a flat bottom H, or, obviously, in lieu of the flat bottom ll, its annular flange portion may be connected to a central hub by a plurality of radial members or spokes, because, in the function of said element 10, the annular flange portion thereof is the only part which acts to effect the discharge of the material from the table or soil carrying element l and in this connection it is preferable to provide radially projecting blades or wings 12 on the circumference of the annular flange of the element, by which provision the material carried on the table or soil carrying element P is brought into engagement with said blades or Wings 12 and causing rotation of the element 10.

The mounting of the rotary drum scraper H1 may be accomplished in any approved manner, but, as shown, it is provided at its center with an upwardly embossed portion 13 which is apertured for the reception of a headed axial stem 14 which is inserted upwardly through the aperture and being of a length so that'it is extended through an aperture provided in a flattened portion 15 of the upper leg member of the frame section 63 intermediate the ends thereof (see Figure 6). The lower portion of the stem 14 is smooth surfaced, on which portion is sleeved rotatably a tubular member 16 which is provided at its lower end with an annularly flanged head H which supports the embossed hub portion of the drum "i0, while the rest of the stem above the lower portion thereof on which the sleeve 16 is rotatably mounted is screw-threaded for the reception of opposed nut members 18 and i9, respectively, the nut i8 being located below and the nut 79 above the flattened portion 15 of the upper leg of the frame section 68, and opposed helical springs 80, of equal strength, being interposed between the nut members 18 and i9 and said flattened portion 75 of the frame section 68. The opposed spring elements 80 are of ample strength and adjustment to support the rotary drum scraper Iii normally in a neutral position where its weight is relieved from the top face of the table or soil carrying element l thereby minimizing wear and practically eliminating resistance to the travel of the annular working portion of the table or soil carrying element l the upper spring element 80 supporting the drum 1i! and the lower spring resisting upward movement of the drum yet yielding to such movement should particles of the material of appreciable size work under the flat bottom I! of the drum. However, if the drum .be openbottomed as when provided with radial members or spokes, as hereinbefore described, particles of material entering beneath the drum will pass out through the openings between the radial members or spokes.

In the modification just hereinabove described, the body frame of the machine may be effectively braced by providing diagonal stays 8| between the ends of the longitudinal frame sections 62 and 63 and the transverse section 68, as shown more clearly in Figure 5. The frame may be further braced by providing a diagonal stay 82 which is attached at one end to the upper leg member of the front longitudinal frame section 62, as at 83, and at its opposite end to the flattened intermediate portion of the upper leg member of the transverse frame section 68, as at 84.

The structure may be further modified by substituting in place of the rotary scraper drum 1!] an endless belt scraper element 85 which is mounted at its opposite looped ends on rollers 86 and 81, respectively, the rear flight of the belt which travels across the rotating table or soil carrying element l in the direction from the roller 86 to the roller 81 being deflected and sup-' ported by a roller 88 which is mounted on a special diagonal frame brace 89 intermediate the ends thereof (see Figure 8), thus giving angularity to this flight of the belt, but the other flight thereof traveling in a straight line between the rollers 86 and 81. The endless belt functions in a manner similar to the rotary drum element ID in that it is provided with lateral wings or blades 90 which are engaged by the material carried on the table or soil carrying element I causing the outer flight of the belt to travel from the roller 86 to the roller 81. In both modifications the tendency of both the drum I0 and the belt 85 is to rotate with the rotating annular table or soil carrying element I thereunder in the same direction that they are caused to travel by the engagement of the material therewith as the latter is carried on the element l In the modification illustrated in Figure 5 to 7, inclusive, the small front ground wheel H is eliminated and instead of providing a pair of rear ground wheels IS a single wheel [6 is provided in line with the longitudinal axis of the machine (see Figures 5 and '7). So, too, inasmuch as the central upper and lower circular plates 5 and 6 are eliminated, a bearing sleeve H connecting the meeting ends of the upper and lower leg members of the respective frame sections is placed on the strut member I I (see Figures 6 and 7). Also, in this modification, the annular table or soil carrying element I has the outer end portions of radial members or spokes I4 secured thereto and the inner ends of said members M being attached integrally to the hub member [3 which is rotatable on the sleeve member H While the structures illustrated in the accompanying drawings and herein described embody practical adaptations of the invention, it is obvious that considerable further modification and alteration may be made within the spirit and scope of the invention as defined in the appended claims.
